Be it known that l, llmvAizn S. EVANS, :i citizen of the United iitutes of rlinerieu, residing :it Richmond, in the county of lleni'ico and Stute of Virginia., have invented certain new and useful improvements-iii .Cheek-Blocks, of which the following is specification. l

This invention relates to certain new und useful improvements in c hoolr blocks, portieulerly those used for, securing; vehicles such as automobiles in fixed position in the our in which they :ire shipped.

ln theshipii ent of automobiles, it is now built-up Condit on, and it is necessary to 4so secure the sinne in le @er in which they :ire-

shippeii, thiit there Shall he absolutely no movement of the automobile independently of the carrying. our. Numerous types-of vehicles are of Very Considerable weight, unil the jarring -sind Chumping to Awhich the een rying Cenis suheeted in travel necessitates ii'in securing 'of' the automobile in the .oarrying' cui', that .the auteinohileniay not he ooine loosened in the carrying our anltlius become rliunnged, or damage other antonio` biies in the carrying cui'.

Patent #1,188,75 granted June 2T, 19ML the object of this inventioiiiieing to provide :i chock block of this general type adapted for use particularly. in connection with heavy automobile trucks and the like that are usually provided with e solici treed, :incl which tread is usually -formed with two treed-surfaces divided by :i groove extenfling oirenin:t'efei'itielly of the tire, the present invention lniving means for engagement in. suoli groove, Iwhereby when the cheek bloei; is positioned. and. Secured, unyluterel iis Well iis longitudinal movement of the vehicle is prevented,

Speeiiically, the present invention enilootlies, in addition tothe tire-engaging ineens; which prevents lateral movement of the automobile, the feature of providing for the ready securing oi.E the chock-block to the )floor o'i the carrying car, us fully set forth.

VIt is preferred to construct this block with fthe heel or ledge E on the rear face of the block to provide for the ready and proper insertion of the securing means such as nails,

- screws or the like which may be employed.

This heel or ledge, as fully set forth in my saidl prior patent, is formed'by making an inout into the rear face of the block, so that the rear face ofthe heel lies in the same plane as the rear face of the block above the point where the incut is made into the block. This incutmay be easily made by a band saw, the cut beinv started at a point suiciently far below t e top face F, of the bloc-k so as not to weaken the block, and turned Aoutward on a gradual curve to produce the ledge E that provides a relatively broad and comparatively plane surface for the insertion of the securing means G, 'enabling the insertion of such-securing means art an angle siderable advantage, the curve at the base of the inout being such as to produce, on the top face of the heel or ledge a surface which acts to center the nail or other device at the proper distance from the rear face of the block', to insure proper positioning of such securing device. This result is due to the somewhat curved top face of the heel or ledge, the nail or other fastening device when rested lightly thereon tending to ride into the base of the gre-ove at the proper point for driving.

Blocks of this type, as fully set forth in my said prior patent, do not interfere with the proper securing of the wheels of the automobile, even though the cars are arranged tandem in the carrying car, with the front wheels of one automobile practically engaging' the rear Wheels of the other automobile, as the ,chock-block lies within the maximum diameter of the wheel tire., If any` 'portion of the chock-block in such case projected beyond the rear face, it would be impossible to position either one or the other of the blocks.`

The rib B acts as a Wedge and serves to prevent any lateral shifting of the automoile, while also acting as a guide to properly position the chock-block with respect to the tire, and when the blocks are fastened down, one in front, and one in the rear of each wheel, as is understood, the Wheel is securely held against movelnent'n either lateral or longitudinal direction. What I claim as new is A chock-block having a Wheel-abutting face, and a projecting rib on said face intermediate'the sides of the block.

In testimony whereof I aix my signature.
